GEORGE E. ADAMS, OF PROVIDENCE, RHODE ISLAND.

BUCKLE.

SPECIFICATION forming part of Letters Patent No. 488,175, dated December 20, 1892.

Application filed May 20, 1892. Serial No. 433,684- (No model.)

To aZZ whom it may concern.-

Be itknown that I, GEORGE E. ADAMS, of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Buckles; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has particular reference to improvements in buckles formed of two parts, the buckle-frame and the cast-d, which are secured together by a spring-catch.

The object of the invention is to produce a spring-catch for buckles which shall be durable in construction, compact in form, and convenient in operation.

The invention consists in certain peculiar features of construction and combination of novel parts, whereby a spring-catch is formed which is more compact than those heretofore constructed as well as more economical in the cost of manufacture, as will be more fully described hereinafter and pointed out in the claim.

Figure 1 represents aview of a buckle and the cast-off detached therefrom to show the construction of the spring-catch. Fig. 2 represents a vertical sectional view of the cast-oft.

Similar numbers of reference designate corresponding parts throughout.

In the drawings 4 indicates a buckle-frame which is provided with the usual clampingdevice for securing the webbing and has a depending member 5 the sides of which are bent over to embrace the tongue of the castofi; the lower central portion of. this member is cut away, as shown in Fig. 1 of the drawings, to provide an entrance 6 for the thumbpiece or depression-stud of the spring-tongue, above the entrance the metal of the member 6 being cut away to form a transverse-slot 7, slightly longer than the width of the springtongue of the cast-oft, to allow the lower end of this spring-tongue to spring slightly upward in order to bring the lower edge of the same into engagement with the shoulders 8 8 formed by the lower edge of the transverseslot.

In the usual form of spring-tongue the metal of the cast-off loop 9 extends upward for about twice the proposed length of the springtongue,this metal is bent transversely and turned back upon itself the lower end being provided with a depression-stud and the lower edge being adapted to engage with the lower edge of the transverse-slot in the buckleframe,-the metal is apt to break across the bent portion and the doubled-piece, or tongue, occupies more space than is desirable in buckles of the present construction, in which the slightest possible addition to the thickness of the web is most important.

In the buckles provided with cast-offs the great objection has been that the member 5 formed a box of considerable thickness to receive the doubled-over spring-tongue.

In carrying out my invention I take a castofi loop 9 having a plate of thin metal 10 extending therefrom,-from the central portion of the plate 10 I stamp out the downwardlyextending tongue 11, which remains joined to the main portion of the plate at the other end, the lower end of the tongue having a short projection. I now strike up this projection, on the lower portion of the plate 10 and that part included within the lines 12, to form the thumb-piece 13 the surface of which slants toward the cast-ofi loop, the lower edges of the plate 10 on each side of this thumb-piece forming shoulders 14 14 which are adapted to engage with the shoulders 8 8 of the member 5 to hold the cast-0flf thereto. Coincident with the striking-up of the thumbpiece 13,0r in a separate operation therefrom, I form the corrugations 15 extending ina direction lengthwise of the plate 10; these corrugations tend to strengthen the whole plate and tongue and in fact make the use of my peculiar spring possible,*I now bend the lower end of the spring-tongue upward from the plane of the plate 10 and finally harden the plate and tongue.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

The combination with a buckle-frame having a depending member with bent-over sides and provided with the slot 7 having an entrance 6 and the shoulders 8, of a east-off, In witness whereof I have hereunto set my consisting of a loop 9, a corrugated-plate 10 hand. extending therefrom, a corrugated springtongue 11 stamped out from said plate and GEORGE ADAMS 5 bent up from the plane of said plate, and a Witnesses:

thumb-piece 13 stamped from the lower por- HENRY J. MILLER, tion of the tongue, as described; M. F. BLIGH.
